A professional approach to numismatic conservation.
From within a state-of-the-art secure facility, NCS uses a variety of proprietary techniques to remove harmful surface contaminants, stabilize and protect a coin’s surfaces, and improve eye appeal. The American Numismatic Association (ANA), the only coin collecting organization chartered by US Congress, and the Professional Numismatists Guild (PNG) have named NCS their conservation service of choice.
What NCS conservation can do
Prolonged exposure to an unstable environment can cause coins of all types to develop haze, spots, encrustation, verdigris, corrosion and tarnish. NCS specializes in the removal of these harmful surface contaminants and the stabilization of a coin’s surfaces.
PVC, glue and dip residues
Residue caused by PVC holders, glue or dip chemicals can often be safely removed by NCS conservation. If left untreated, these residues can permanently damage a coin’s surfaces. Many modern coins have been sold in packaging that contains PVC.
What NCS conservation cannot do
Though NCS conservation benefits many coins, there are certain problems that cannot be remedied, such as corrosion, wear, scratches, and white “milk” spots. NCS does not make repairs and, likewise, cannot undo mechanical alternations.
